What we're seeing today is a (digital) supply chain attack against code that is used by many crypto projects. JS library attacks aren't new, but this one seems worse than usual because the library is "hot loaded" rather than pinned to a version with an integrity check hash.

Smaller signatures not only save on blockchain space and fees, but make it easier for wallets to estimate the fee accurately. It also means the nonce generation is done in the same way as Bitcoin Core, which further minimizes trust in the implementation.

Great guide to running the Fulcrum Electrum server on an RPi, using zram for faster indexing 🚀

We are happy to announce that Fulcrum is officially part of a #Bitcoin bonus guide! It is an alternative to Electrum servers, being the most performant and completely worth the sync time!

@openoms Both native Segwit and Taproot working well. The developer appears relatively chain agnostic. It would be interesting to see if ZRAM can improve indexing time with the Fulcrum fast sync parameter!

@BTCsessions @JakobFN @SparrowWallet The need to backup the wallet file or the output descriptor is the key “gotcha” with multisig wallets. It does get discussed regularly, but we can always do more.

Replace By Fee is a great tool to master - you can not only save on fees, but recover from mistakes. Low fee tx taking too long to confirm? RBF it to a higher fee rate. Sent a transaction to the wrong address? If it's still in the mempool, just RBF to the right one.

@EthanBitcoin @discoveringbtc It’s input & output order, which personally I needed last year for testing/bugfixing. Regardless, been meaning to add it for years, given you can edit every other part of the tx already. It’s also useful for docs & some want it for privacy reasons. I have no interest in ordinals.

If you need a place to start, here is the head of the BIS talking about the future of cash. CBDCs mean every transaction is visible to the state, your money can be confiscated arbitrarily, and there is no lower bound on negative interest rates.

In case it wasn’t obvious to you yet, here’s the head of the Bank of International Settlements clarifying that the difference between cash and CBDCs is that the former provides privacy while the latter gives the central bank “absolute control” 🥶

Is it possible for an address index to be performant in both initial indexing and handling the needs of deep wallets? I believe so! Hopefully in learning from the choices these implementations have made, we can improve performance to match our growing needs. 🚀

The main pushback to half-aggregrate CISA seems to be that it doesn't do enough, but I think that ignores the incentives.

@reardencode @gladstein @1440000bytes The ~8% reduction in fees is for the current average of 2-3 inputs and outputs. An incentive to reduce fees in a high fee rate environment would likely increase this, while reducing the effectiveness of the common input ownership heuristic.

@KeithMukai @vnprc @SparrowWallet @SwanBitcoin @BraiinsPool A reason BIP47 has adoption is because it is compatible with light clients, such as those that support the Electrum protocol. Silent Payments is not so much an updated protocol as one with a different set of tradeoffs, one of which is lack of native light client support.

@murchandamus @josibake @reardencode @ajtowns @gladstein @1440000bytes A few percent cheaper may not seem like much, but I have no doubt Sparrow would be defaulting to Taproot for singlesig wallets if half agg CISA was supported. As it stands, Native Segwit costs much the same with a much larger anonset.

@EthanBitcoin @discoveringbtc Docs frequently include screenshots showing the transaction diagram. Specific ordering there can make things easier to understand. Personally I believe that random is always better for privacy, but my philosophy is have good defaults but don’t dictate. Can’t know every use case

@ODELL A better approach is to have clear separation between parties providing the wallet software, and the server it connects to. Ideally use your own node/server, but if you connect to a public server use one run by a 3rd party with a record of supporting privacy. See @SparrowWallet

@CasaHODL Unfortunately we are likely to see more of this in future as Bitcoin holdings grow in value. This is where geographically separated multisig wins. If this attack worries you, it may be time to start skilling up.

1/ Sparrow is taking a standards based approach to privacy. The Payjoin standard (BIP78) is relatively new, but already supported by @BTCPayServer and several wallets. Hardware wallets should be able to sign Payjoin transactions too ( @COLDCARDwallet support soon!).
